'Movie' is related to 'Actor' in the same way as 'Magazine' is related to '______'.

Writer

The answer is Writer.

Here's the reasoning:

• Movie and Actor are related in the sense that an Actor performs in a Movie.
• Similarly, Magazine and Writer are related in the sense that a Writer creates content (articles, stories, etc.) for a Magazine.

Therefore, based on the analogy, the word that best completes the sentence is Writer.
